Videos on twitter won't play on firefix. I tried on edge and they worked just fine.

I have tried doing the firefox refresh thing and safe mode, still couldn't play twitter videos.

Make sure you are not blocking content.

One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

You can check the Web Console for messages about media content.

Thank you for the response! I do not think tracking protection is the issue, seeing as how there is no shield icon as described in the info you linked.

Here is what I got from the web console:
